Question

1. which of the following statements is true about the equilibrium in the demonstration?

a) equilibrium is reached when the amount of water moving back and forth is large.
b) equilibrium is reached when the amount of water moving back and forth is small.
c) equilibrium is reached when the amount of water moving back and forth is equal.

1. what point is equilibrium reached?

(choose two answers)
a) the concentrations of the reactants and products are equal.
b) the concentrations of the reactants and products are moving toward equal.
c) the rate of the reverse reaction is greater than the forward reaction.
d) the rates of the forward and reverse reactions are equal
e) the concentrations of the reactants and products have stabilized.

Explanation:

1. In a system at equilibrium, the forward and reverse processes occur at the same rate. For the movement of water back - and - forth, equilibrium is when the amount moving in each direction is equal.
2. At equilibrium, the rates of the forward and reverse reactions are equal, and the concentrations of reactants and products stabilize (but are not necessarily equal).

Answer:

1. C. Equilibrium is reached when the amount of water moving back and forth is equal.
2. D. The rates of the forward and reverse reactions are equal; E. The concentrations of the reactants and products have stabilized.
